Description

Automatic ventilation control system for each room of a residential building {AUTOMATIC VENTILATION CONTROL SYSTEM FOR EACH ROOM IN A RESIDENTIAL BUILDING}

The present invention relates to a system for controlling indoor ventilation of a residential building such as an apartment house, and more specifically, to provide a ventilation control system that considers temperature and humidity for each room in the residential building itself, thereby providing a comfortable dwelling for residents. It relates to an automatic ventilation control system for each room of a residential building to promote living.

In the indoor space of a residential building, the concentration of carbon dioxide increases according to the breathing of occupants, and when the concentration of such carbon dioxide exceeds 1,000 ppm, it may cause health problems for the occupant. In addition, various hazardous chemicals continuously emitted from indoor building materials and furniture and pollutants generated by occupants' actions continuously accumulate indoors. Therefore, it is necessary to ventilate the room at regular intervals when residents are in the room.

In addition, people in general seek an environment for leading a more pleasant life as their economic ability increases.

Therefore, residents of residential buildings such as apartment houses, as shown in Figure 1, in order to make the indoor environment comfortable, such as various home appliances, such as air conditioners or fans and dehumidifiers for hot and humid summers, heaters and humidifiers for cold and dry winters It is common to arrange an air purifier to remove fine dust introduced into the room due to ventilation, etc. in the indoor space, and to make efforts to create a pleasant indoor environment by individually controlling each home appliance whenever necessary.

However, the installation of these home appliances not only hinders the aesthetics of the room and the efficient use of space, but also the individual control of these appliances causes inconvenience in use, while the operation of each appliance independently reduces the efficiency of use. There are problems that arise. For example, in a hot summer, when the air conditioner is operated at an appropriate temperature and ventilation is provided to discharge carbon dioxide generated in the room due to the breathing of occupants, it is not easy to set a comfortable temperature while consuming more energy for the air conditioner. do. As such, since ventilation, environmental factors such as temperature and humidity mutually influence each other, it is very difficult for residents to control them in real time to maintain a comfortable indoor environment.

Furthermore, residential facilities such as apartment houses consist of spaces in which a number of rooms, such as master bedrooms, living rooms, and bedrooms, of different sizes are partitioned, and the object of environmental control varies depending on whether each room is occupied or not. For example, in a state where residents are only in the living room, it may be necessary to ventilate the living room, but it is not necessary to ventilate the rest of the rooms that are not being used. In addition, the temperature and humidity for a comfortable environment vary from person to person.

However, generally installed ventilation systems have a problem in that energy is wasted unnecessarily because ventilation is uniformly performed for all spaces of a residential facility.

KR 10-1565068 B1

The present invention is to solve the above problems of the prior art, by enabling independent ventilation for each room, eliminating energy waste due to continuous ventilation in empty rooms where residents are absent, and considering the number of people in the room and the indoor environment. It is intended to provide an automatic ventilation control system for each room of a residential building that enables efficient and intensive energy use by enabling ventilation.

In addition, according to the present invention, a pleasant indoor environment is continuously maintained by automatically performing ventilation considering the environmental conditions of the outside air, and the setting and control of the indoor environment are linked with an indoor controller and a smartphone to facilitate use and management by residents. It is intended to provide an automatic ventilation control system for each room of a residential building that can improve convenience.

According to the most preferred embodiment of the present invention for solving the above problems, a ventilation unit for air supply and exhaust and individual environmental conditions required by each room are input, and the current environmental condition for each room is displayed. It is composed of a controller and a control device that controls the operation of the ventilation unit according to the set value input to the controller, so that each room is independently ventilated, and each room has a carbon dioxide concentration sensor, a room temperature sensor, and a room humidity sensor. There is provided an automatic ventilation control system for each room of a residential building, characterized in that it is installed.

As an embodiment of the ventilation unit, a temperature and humidity compensator composed of a temperature control device for controlling the temperature of pure outdoor air supplied through an air supply pipe communicating with the outside and a humidity control device for adjusting humidity, and passing through the temperature and humidity compensator Thus, a ventilation unit is provided with a distributor for distributing, supplying, or shutting off corrected outdoor air of which temperature and humidity are adjusted to each room.

At this time, the air supply pipe may be branched into a first branch pipe and a second branch pipe so that the first branch pipe passes through the temperature and humidity compensator and is connected to the distributor, and the second branch pipe bypasses the temperature and humidity compensator, In this case, the corrected outdoor air supplied through the first branch pipe and the pure outdoor air supplied through the second branch pipe are mixed and supplied to each room.

In addition, a heat exchanger using exhausted indoor air may be installed in the ventilation unit, so that the pure outdoor air supplied through the air supply pipe 140 passes through the heat exchanger and then passes through the temperature and humidity compensator so that indoor heat energy is not wasted. can make it not

In addition, the distributor measures the supply amount of corrected outdoor air for each room, distributes the amount of corrected outdoor air calculated by the control device out of the ventilation amount, and supplies it to each room.

As another embodiment, by further installing a motion recognition sensor for checking whether a resident is present or not in each room, it is possible to set different environmental conditions depending on whether the resident is present or not.

According to the present invention, since the ventilation control system itself is embedded in a wall of a building without installing individual home appliances, the indoor space available to residents is not reduced and the interior aesthetics due to the installation of the home appliances are not impaired.

In addition, the present invention allows each room to be individually and independently automatically ventilated for a residential building having a plurality of rooms, so that each occupant of each room can set indoor environmental conditions suitable for him/herself and maintain the condition continuously. By doing so, it improves the quality of life of residents.

In addition, the present invention not only operates the ventilation unit in conjunction with external air quality, but also maximizes energy efficiency by varying ventilation conditions depending on whether each room is occupied.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, in the description of the present invention, when the technical idea of the present invention is blurred or unclear due to the detailed description of the known configuration, the description of the configuration of the above known will be omitted.

2 is a conceptual diagram of an automatic ventilation control system according to an embodiment of the present invention.

The present invention is to automatically control the indoor ventilation of a residential building having a plurality of rooms consisting of independent spaces such as a living room and a bedroom so that a pleasant environment can be continuously maintained to promote a pleasant quality of life and a healthy residential life for residents. is to make it possible

As shown in FIG. 2, the present invention for this purpose includes a ventilation unit 100 that allows ventilation through air supply and exhaust, a controller 300 that allows residents to set environmental conditions, and set environmental conditions. It is configured to include a control device 200 that automatically controls the operation of the ventilation unit 100 to continuously maintain.

Specifically, the controller 300 is provided with an input window 310 for inputting and setting environmental conditions determined by the occupants of each room as comfortable conditions and a display window 320 indicating the current environmental condition for each room, When a resident inputs and sets individual environmental conditions required by each room in the input window 310, the controller 200 checks the current environmental condition in each room and displays it through the input window of the controller 300 ( 310), the required amount of ventilation and the temperature and humidity of air supplied for ventilation are calculated, and the ventilation unit 100 is operated so that ventilation for each room can be independently performed.

To this end, a carbon dioxide concentration sensor 401, an indoor temperature sensor 402, and an indoor humidity sensor 503 are installed in each room, and a motion recognition sensor 404 for checking whether or not a resident is in the room may be further installed. .

The controller 300 may be individually installed in each room, or may be installed together or independently in a space such as a living room to be integratedly managed. In addition, the controller 300 can adjust or check indoor environmental conditions even from the outside in conjunction with a smartphone.

The automatic ventilation control system of the present invention configured as described above should be installed in a wall of a building or installed on a ceiling so that the indoor space available to residents is not reduced.

The ventilation unit 100 is provided with an air supply pipe 140, a temperature and humidity compensating unit 110, and a distributor 145 for distributing and supplying or blocking some of the supplied air according to the amount of ventilation required in each room.

The air supply pipe 140 is a conduit for supplying outdoor air to the indoor through communication with the outside, and by providing a filter box 120 in which a fine dust filter is built-in, the air supplied to the room can reduce the concentration of fine dust so as not to harm the human body. It is desirable to minimize

Of course, each room has an exhaust port 152 for discharging indoor air to the outside, an exhaust duct 151 connected to the exhaust port 152, and a heat exchanger 113 connected to the exhaust duct 151 and described below. When installed, an exhaust pipe 150 communicating with the outside of the residential building via the heat exchanger 113 is installed.

After the pure outdoor air supplied through the air supply pipe 140 passes through the heat exchanger 113 and absorbs the energy of the indoor air, all or part of it passes through the temperature and humidity compensator 110 and is supplied to each room, or the temperature and humidity compensator ( 110) is supplied to each room. For example, in summer or winter, all or most of the pure outdoor air passes through the temperature and humidity compensating unit 110, and in spring and autumn, all or most of the pure outdoor air passes only through the heat exchanger 113, and then the temperature and humidity compensating unit 110 ) and is directly supplied to each room.

To this end, the air supply pipe 140 is branched into a first branch pipe 140a and a second branch pipe 140b between the heat exchanger 113 and the temperature and humidity compensating unit 110, and among them, the first branch pipe 140a The silver passes through the temperature and humidity compensator 110 and is connected to the distributor 145. An air supply duct 147 is installed between the distributor 145 and the air supply inlet 148 for injecting air into the room.

However, the second branch pipe 140b is connected to the air supply duct 147 after bypassing the temperature and humidity corrector 110 . A damper 146 is installed at an end of the second branch pipe 140b connected to the air supply duct 147 to control the amount of air passing therethrough.

The temperature and humidity compensator 110 is composed of a temperature control device 111 and a humidity control device 112.

The temperature controller 111 adjusts the temperature of the pure outdoor air supplied through the air supply pipe 140, more specifically, the first branch pipe 140a. For example, through the thermostat 111, air heated in cold winter and reduced in hot summer is supplied to the room.

The humidity control device 112 also adjusts the humidity of the pure outdoor air supplied through the first branch pipe 140a of the air supply pipe 140, like the temperature control device 111. For example, air humidified in dry winter and dehumidified in humid summer is supplied to the room through the humidity controller 112 .

That is, the air supplied to the first branch pipe 140a passes through the heat exchanger 113 and the temperature and humidity compensating unit 110 to form corrected outdoor air in which the temperature and humidity are actively adjusted with respect to the outdoor air, and supplies it to the room. . In contrast, the air supplied to the second branch pipe 140b passes through the heat exchanger 113 so that pure outdoor air itself whose temperature is adjusted by the absorbed heat energy can be supplied to the room.

In this way, the corrected outdoor air of which temperature and humidity are adjusted together and the pure outdoor air of which only the temperature is adjusted by the heat exchanger 113 are mixed in an appropriate ratio so that ventilation suitable for the environmental conditions required differently for each room can be achieved. .

To this end, an outside air temperature sensor 141 and an outside air humidity sensor 142 are installed in the air supply pipe 140 before branching to check the temperature and humidity of the pure outdoor air. In addition, the distributor 145 is provided with a metering means for checking the individual supply amount of corrected outdoor air supplied to each room, and a corrected temperature sensor 143 and a corrected humidity sensor 144 for checking the temperature and humidity thereof.

The operation of the automatic ventilation control system of the present invention described above will be described.

First, when the carbon dioxide concentration set in each room is exceeded, the control device 200 calculates the ventilation amount for each room and the total air supply amount required to adjust it to the set concentration.

The set value of the carbon dioxide concentration serving as the ventilation standard in each room is made through the input window 310 of the controller 300, and this setting can be made differently depending on whether or not a resident is in the room.

For example, when a resident is staying in the room, set it to 700 ppm or less, which does not cause health problems even when staying for a long time, or set it to 450 ~ 500 ppm to feel comfortable more actively. to increase the efficiency of use.

Confirmation of the occupancy and exit of each room is by the motion recognition sensor 404 installed embedded in the ceiling of each room, and the control device 200 receiving the signal about the occupancy from the motion recognition sensor 404 causes the ventilation unit 100 to stand by in its corresponding operation mode.

In addition, the temperature and humidity to be maintained in each room are also set through the input window 310 . At this time, since the temperature and humidity that each person feels comfortable may be different, the setting of the above temperature and humidity may be set differently for each room and depending on whether or not the room is occupied.

For example, in the low-temperature, dry winter, in room 1, the temperature is set to be 23℃ or higher when re-entering and 10℃ or higher when leaving, and the humidity is set to 40% or higher when re-entering and 20% or higher when leaving, respectively. In the other second room, the temperature can be set to 20 ° C or higher when re-entering and 10 ° C or higher when leaving the room, and the humidity can be set to 45% or higher when re-entering and 20% or higher when leaving the room.

In addition, in the high-temperature and humid summer, in room 1, the temperature is set to be 26℃ or less when re-entering and 29℃ or less when leaving, and the humidity is set to 60% or less when re-entering and 70% or less when leaving, respectively. In the second room, where the temperature is different, the temperature can be set to 25 ° C or lower when re-entering and 28 ° C or lower when leaving the room, and the humidity can be set to 55% or higher when re-entering and 65% or lower when leaving the room.

Of course, in the interseason between spring and autumn having appropriate temperature and humidity, the operation of the temperature and humidity corrector 110 may be stopped and only the carbon dioxide concentration may be set.

Next, the controller 200 checks the temperature and humidity of the pure outdoor air whose temperature is adjusted only through the heat exchanger 113 through the outdoor air temperature sensor 141 and the outdoor air humidity sensor 142 installed in the air supply pipe 140. And, for the amount of ventilation required in each room, when the above-mentioned pure outdoor air is supplied, the amount of change in temperature and humidity in the room is predicted. In addition, after calculating the amount of energy to adjust it to the set temperature and humidity, the temperature and humidity of the air passing through the first branch pipe 140a are adjusted based on this.

As described above, the calibrated outdoor air whose temperature and humidity are adjusted while passing through the first branch pipe 140a is mixed with the pure outdoor air passing through the second branch pipe 140b to meet the temperature and humidity required in each room. As it is sent to the air supply duct 147 connected to each room, the first adjustment of the temperature and humidity by the temperature and humidity corrector 110 is the amount, temperature, and humidity of pure outdoor air to be supplied through the second branch pipe 140b. etc. must be taken into account. Whether or not the corrected outdoor air to pass through the distributor 145 is adjusted to an appropriate temperature and appropriate humidity depends on the corrected temperature sensor 143 and the corrected humidity sensor 144 provided in the distributor 145 .

When it is confirmed that the corrected outdoor air in the first branch pipe 140a has been adjusted to an appropriate temperature and appropriate humidity, the controller 200 calculates the mixing ratio of the corrected outdoor air to be supplied to each room and the pure outdoor air, and calculates the mixing ratio according to the mixing ratio. Accordingly, the distributor 145 connected to the first branch pipe 140a and the damper 146 connected to the second branch pipe 140b are operated so that air of which temperature and humidity are secondarily adjusted is supplied to each room.

Accordingly, in each room, while external air having an individually set temperature and humidity is supplied through the air supply port 148, the indoor carbon dioxide concentration is kept below a set value so that a comfortable indoor environment can be continuously maintained.

A non-explanatory numeral '130' is an air supply fan installed to facilitate the supply of outside air to the air supply pipe 140.

In the above, the present invention has been described in detail with reference to specific embodiments, but since the above embodiments are merely examples to make the present invention easier to understand, those skilled in the art are within the scope of the technical idea of the present invention. It is obvious that it will be possible to carry out various modifications within. Therefore, it will be said that such modifications fall within the scope of the present invention as described in the claims.
